Title: Mountains


1
Mountains
  • Geology 12 - Chapter 20

2
Orogeny
  • Mountains are the result of tectonic forces to
    rock .
  • Orogeny is the process by which a mountain is
    built.
  • Mountain-building on continents is associated
    with intense deformation, folding, and faulting,
    usually along convergent plate boundaries.

3
Ranges versus Belts
  • Ranges are groups of mountain peaks or ridges
    that form areas bordered by valleys or rivers.
  • Mountain belts are long chains of mountain ranges
    that can extend across continents or along their
    edges.

4
7 Major Mountain belts
  • North American Cordillera backbone" of North
    America, Central America and South America
  • Andes South America
  • Appalachians/Caledonides spanning continents
  • Pyrenees Europe between France and Spain
  • Alps - Europe
  • Urals - Russia
  • Himalaya Asia and includes Everest and K2

5
Belts
  • Typically 1000 of kilometers long and 100
    kilometers across (wide)
  • Parallel to continental coastlines
  • The taller the mountains the younger (example
    steeper rocky mountains are younger than the
    rounded Appalachian) WHY?

6
Rockies
7
  • The American Cordillera is a series of steep
    mountain ranges that rim the western edge of
    North and South America it is one of the longest
    mountain belts in the world.
  • It includes the Rocky Mountain range!

8
Andes
  • The Andes Mountains are located in South America,
    running north to south along the western coast of
    the continent.
  • The Andes Mountains are the longest and one of
    the highest mountain ranges in the world.
  • They are located in South America and stretch
    4,500 miles from north to south, along the west
    coast of the continent.

Appalachians
11
Appalachians
  • The Appalachian Mountains are a vast system of
    mountains in eastern North America. The range
    is mostly located in the USA but extends into
    southeastern Canada.
  • 160 to 480 km wide, running from NFLD 2,400 km
    south-westward to central Alabama
  • The system is divided into a series of ranges.
    Individual mountains averaging around 3,000 ft
    (900 m).
  • The highest of the group is Mt. Mitchell in NC
    2037m high.

13
Caledonides
  • The Caledonides are the ancient mountain range
    that stretched from the Appalachians in North
    America, through the Atlantic plates, to
    Scandinavia.
  • It was caused by the closure of the Iapetus Ocean
    when the continents and terranes of Laurentia,
    Baltica and Avalonia collided. http//en.wikipedia
    .org/wiki/Caledonian_orogeny
  • They are a remnant of a former age, the result of
    continental drift.

15
Urals
  • The Ural Mountains runs roughly north and south
    through western Russia.
  • They are sometimes considered as the natural
    boundary between Europe and Asia.
  • Stretching 2,400 km north and south from the
    Arctic tundra to the deserts of the Caspian Sea.
  • Has the highest peaks, Naroda and Telpos-Iz.

Urals
17
Alps
  • The Alps are in Europe stretching from Austria
    and Slovenia in the east to Italy, Switzerland,
    Liechtenstein and Germany to France in the west.
  • Alps (Latin albus meaning white or altus meaing
    high)
  • The highest mountain in the Alps is Mont Blanc
    (4808m) on the French-Italian border.

19
Pyrenees
  • The Pyrenees are mountains in southwest Europe
    that form a natural border between France and
    Spain.
  • They separate the Iberian Peninsula from France,
    and extend for about 430 km from the Atlantic
    Ocean to the Mediterranean Sea.
  • Older than the Alps.

21
Himalaya
  • Together, the Himalaya mountain system is the
    planet's highest and home to the world's highest
    peaks including Mount Everest.
  • To comprehend the enormous scale of Himalayan
    peaks, consider that Aconcagua in the Andes at
    6,962 m, is the highest peak outside the
    Himalaya, while the Himalayan system has over 100
    separate mountains exceeding 7,200 m.
  • The Himalayas stretch across 6 nations Bhutan,
    China, India, Nepal, Pakistan and Afghanistan.
